Question

A farmer has a rectangular field with length 225 m and breadth 150 m. Find the length of the wire needed to fence around the field.​

Answer 1

Answer:

750

Step-by-step explanation:

Length of the wire needed = total length of boundary.

In closed figures, here, rectangle

Total length of boundary = perimeter

Thus, wire required:

=> perimeter of rectangular field

=> 2(length + breadth)

=> 2(225m + 150m)

=> 2(375m)

=> 750 m

Length of the wire needed to fence around the field is 750m

Answer 2

Given:

• Measure of rectangular field - 225 m (length) and 150 m (breadth)

To find:

• The length of wire required to fence around the field.

Formula used:

• Perimeter of rectangle = 2 × (length + breadth) units.

Solution:

Substituting the measures of the field in the formula,

→ 2 × (length + breadth) units

→ 2 × (225 + 150) m

→ 2 × 375 m

→ 750 m.

Therefore, 750 metres of wire is required to fence around the field.

Some formulas to know:-

• Area of rectangle = length × breadth sq.units
• Perimeter of square = 4 × side units
• Area of square = side × side sq.units
• Perimeter of circle = 2πr units
• Area of circle = πr² sq.units
• Perimeter of parallelogram = 2 × (a + b) units
• Area of parallelogram = base × height sq.units
• Perimeter of rhombus = 4 × side units
• Area of rhombus = 1/2 × diagonal (1) × diagonal (2) sq.units
• Perimeter of equilateral triangle = 3 × side units
• Area of equilateral triangle = √3/4 × a² = 1/2 × side × height sq.units
• Perimeter of trapezoid = (Sum of all sides) units
• Area of trapezoid = 1/2 × height × (sum of parallel sides) sq.units
